Book Description
In this monograph, a finite difference algorithm for study- ing two dimensional wave breaking in the vertical plane is developed. The essential feature of this algorithm is the combination of the Volume-of-Fluid (VOF) technique for arbi- trary free surfaces and the k-E turbulence model. This me- thodology allows a self-contained study for wave transforma- tion processes in shallow water before, during and after breaking. This capability is illustrated in several calcula- tions. This book will be of interest for final year graduates, postgraduates and researchers working in the fields of tur- bulence modelling, wave hydrodynamics, coastal engineering, and oceanography of coastal regions.

Book Description
Wave breaking represents one of the most interesting and challenging problems for fluid mechanics and physical oceanography. Over the last fifteen years our understanding has undergone a dramatic leap forward, and wave breaking has emerged as a process whose physics is clarified and quantified. Ocean wave breaking plays the primary role in the air-sea exchange of momentum, mass and heat, and it is of significant importance for ocean remote sensing, coastal and ocean engineering, navigation and other practical applications. This book outlines the state of the art in our understanding of wave breaking and presents the main outstanding problems. It is a valuable resource for anyone interested in this topic, including researchers, modellers, forecasters, engineers and graduate students in physical oceanography, meteorology and ocean engineering.

Book Description
Ocean Wave Dynamics is the most up-to-date book of its kind on the three main processes responsible for the generation and evolution of ocean waves: (i) atmospheric input from the wind, (ii) wave breaking and (iii) nonlinear interactions.Ocean waves are important for many reasons. They are the major environmental impact on in the design of coastal or offshore structures. Ocean waves are also fundamental to the processes of coastal flooding and beach erosion. They will play a major role in storm related coastal flooding which will rise in frequency as a result of sea level rise. Ocean waves are also an important part of the coupled ocean-atmosphere system. They determine the roughness of the ocean surface and hence have an impact on winds, fluxes of energy, gases and heat to the ocean and even the stability of ice sheets.Containing the latest research on ocean waves, it is a valuable resource for an overview of knowledge in this important field.Related Link(s)

Book Description
Wave breaking is a commonly occurring phenomena associated with wave motion in fluids, often inducing significant effects which are of fundamental and technological importance, A familiar illustration is provided with white-capping and microbreaking of the wind-driven ocean sUrface waves, which is believed to play an important part in the transfers of momentum, mass and heat across the air-sea interface, as well as in the production of underwater ambient noise and augmented microwave backscatter. The enhanced hydrodynamic forces associated with the breaking of the more energetic ocean wave components constitute a significant challenge in ocean engineering, coastal engineering and naval architecture. Other less conspicuous but equally important manifestations are the breaking of internal waves and the fila mentation of vorticity interfaces. Despite recent theoretical and observational progress towards a more complete understanding of wave breaking, mathematical descriptions of its onset and consequences are presently lacking. The aim of this Symposium was to bring together theoretical and observational expertise, with the goal of determining the current state of knowledge of wave breaking and providing a stimulus to future research. The Symposium focused on water waves of all scales from capillary waves to ocean swell, but also considered internal waves and the filamentation of vorticity interfaces. Specific topics included were: Fundamental theoretical studies; wave instabilities; routes to breaking. Models of wave breaking. Field observations, including statistical information. Laboratory studies. Shoaling waves, breaking waves on currents, breaking induced by the motion of a ship.

Book Description
Laboratory measurements of wave shoaling and breaking on an ebb current were made in an idealized inlet in a wave basin. The experiment arrangement, procedures, and data analysis are described. The wave and ebb current measurements showed increased shoaling and breaking (compared to no current, shifting of the spectral peak to lower frequencies, and energy dissipation concentrated at the spectral peak and higher frequencies). The measurements were used to evaluate and develop formulations of wave dissipation on a current for application to a spectral wave model. Whitecapping dissipation formulations underpredicted breaking on a current in shallow water, whereas the bore-based wave dissipation relationship of Banjes and Janssen and a relationship developed in this study provided good estimates of wave-height decay on an ebb current Tables of the wave and current parameters are provided as an appendix.

Book Description
Luna loves the sea and the gifts she finds every day on the shore. But one day a wave sends her life adrift, in this touching, funny novel about grief, love, and friendship Thirteen-year-old Luna lives in a small town on the coast of Tuscany. She is smart and funny. And she is albino. When her brother Luca drowns in a surfing accident, Luna's mother retreats into herself. At school, stricken by her loss yet determined to carry on, Luna makes a new friend and ally, the eccentric Zot, a boy from Chernobyl. Luna believes that Luca still speaks to her through a whale bone washed up on the shore. In truth, this is part of a ruse that has been orchestrated by Sandro, Luca's former teacher, as a misguided way to assuage the guilt he carries with him. Luna's fantasies clash with the lies—even the well-intentioned ones—of the adult world in this touching, droll novel by the author of Live Bait (Other Press, 2014). Luna is an unforgettable character—vivid, stubborn, highly imaginative, determined to become her own person—who will appeal to readers of all ages.

Book Description
This book fills a gap in knowledge of breaking waves and their influence on the generation of marine fluxes from ocean surfaces. Based on published data as well as on the author's experience, the text explores in detail the relationship chain of breaking waves, whitecaps coverage, rate of wave energy dissipation, amount of aerosol fluxes rising from a given sea basin, and possible seasonal variations.

Book Description
Random waves are the most important constituent of the sea environment. They make the design of maritime structures quite different from that of structures on land. In this book, the concept of randomness in waves for the design of breakwaters, seawalls, and harbor structures is fully explored for easy comprehension by practicing engineers. Theoretical aspects are also discussed in detail for further studies by graduate students and researchers. Several additions have been made to this second edition, including a new chapter on extreme wave statistics.
